SPECIFICATION forming part of Leners Patent No. 349.749,'da't'ed september 28,1886 application nien Sapman@ il; Issa serial No. 106,163. (Nomael.)

To all whom it may concern:

Be it known that I, FRANK RosERRooK, of Elmira, in the county` of Chemung and State of New York, have invented a new and Improved Incnbator, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for hatching eggs, and to provide for a perfect distribution of the heat in the incubator and other necessities `for insuring a rapid and safe development of the embryos. Y

The invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming part of this speciiication,

, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my improved incubator on the linezz, Fig. 2. Fig. 2 is a plan View of the upper part of the boiler with the top plate removed. Fig. 3 is a` cross-sectional elevation of the incubator on the line a' er, Fig. 1. Fig. 4 is a sectional plan view of the same on the line y y, Fig.V 1. Y

The incubator-casing, A,- is made of wood with hollow walls, which may be lined with paper, felt, dmc., or may be filled with some suitable noncondnctor of heat.' The-casing is provided on two or on all sides with hinged or sliding doors, A, having glass panels, so that the interior of the casing can be seen plainly, and below t-he doors the casing is pro vided with longitudinal windows, A3, one end of each of which is open, but can be closed by means of a slide, A". These openings are provided for the purpose of admitting-fresh-'air into the incubator. Cleats B are hung onpins B on the innersides of the casingAby means of hangers B2 in such a manner that the said Y cleats will be slightly inclined from the sides toward the middle longitudinal partition, C, of the casing. To permit of adjusting the cleats higher or lower the hangers B2 are pro-. vided with two or more apertures, through which the pins'B can be passed. The eggcarrying drawers or trays D rest and slide on these cleats B, and consist of a frame, O', with a wire-netting or perforated or slatted bottom, C2, which is divided into a series of compart- Vments or'spaces by `longitudinal strips C, ex-

tending longitudinally lof and having their ends secured to the'frame, each compartment orsubdivision being of such size as to receive one row of eggs. The egg-drawers D are so located' that they can be Vpassed into the casing yAwhen the doors A2. are opened.

The hot-water tank consists of a dat vessel, E, resting on the upperpart of the casing A, and subdivided,by longitudinal and transverse partitions E E2, into a series -of channels, in which the hot water circulates in a manner that will be fully described and set forth herevinafter.

The tank E is provided with an opening, D, for the ventilation-flue, in which a dampervalve, J, is provided. Byt means of a tube, E3, the flat tank E is connected with` thetop of an upright cylindrical vesselor boiler, F, provided with a longitudinal conical' ue, F, below which a lamp, G, a gas-burner or other suitable source ot' heat,'rests upon a bracket,

G. A pipe, F2, leads from'the lower part of 7- the eylindricalvessel F to a serpentine waterpipc, F, in the casingrjA, lwhich pipe is connected at the opposite end with the ilat tank or vessel E by means of pipes F4, so that the hot water can circulate in the vessel E, the pipe E3, the vessel F, and the pipes F2, F, and F", wherebya very large radiating surface is obtained, and ,theair in the'casing A will be heated thoroughly-'and uniformly. Flat vessels I-I, containing-water, are placed upon the serpentine pipes '.'F3,so that the water in these vessels will be'revaporated, thus producing the moisture required.

The space below the serpentine pipes F3 in the casing is to beused as atemporary nursery.

for the young chickens. vThe hot water rises in the boiler F and circulates through'the pipe E3 and passes into the vessel E. It then passes into the outer channels ofthe same, and thus heats the casing at the sides and ends, where it is most exposed to the cold surrounding air. It then passes through .the inner channels, and then through the pipes F4 andthe serpentine pipes F3 back to the boiler F. the easing is thus heated uniformly and most The air in Y IOO where the most heat is required-that is, at

the sides which have glass doors-and thus are colder than the interior part of the casing.

Itis of great importance to be able to Watch the interior of the casing without opening the door every time the progress is to be observed. This is only possible if the casing is provided with the glass doors, or, if desired, with. fixed glass panels, glass doors being preferred.

By means of the hangers B2 the trays can be adjusted to a greater or less distance from the bottom of the vessel E, and can thus be exposed to more or less heat radiated from the bottoni of the VesselE, accordingly as may be necessary.

I make no claim in this application to the egg-trayv shown and described, as it forms the subject-matter of my application, iiled May 26, 1885, and patented August 11, 1885, No.

Having thus described myinventi0n,what I claim as new, and desire to secure by Letters Patent, is

1. In an incubator, the combination, with a boiler, of a hot-water tank located above the egg-chamber and divided by partitions into channels for conducting the water first to both sides of the tank and then toward the middle 0f the same, and communicating with the upper and lower portions of the said boiler by means substantially as shown and described.

for the purpose of conducting the Water from said tank back to the boiler, substantially as herein shown and described.

3. In an incubator, the combination, with a boiler, of a hot-water tank divided by partitions into channels that conduct the Water rst to the outside of the tank, then back to the center, a system of pipes connected with said hot-water tank and With the boiler for the purpose of conducting the water from said tank back to the boiler, and water-pans resting upon said pipes, substantially as herein shown and described.

4. The combination, with the trays C2, of the hangers B2, provided with a series of apertures, and of the pins B, substantially as herein shown and described.

, FRANK ROSEBROOK.
